BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an office building or a base station house, and in particular to an office building or a base station house capable of regulating indoor temperature and lighting by making use of the thin film solar cells in achieving energy conservation.

2. The Prior Arts

Along with the global concern about environment protection, and worldwide acceptance and implementation of the concept of “energy conservation and carbon reduction”, therefore, the development and utilization of regenerated energy resources has been the keypoint of development for various countries of the world. Among the regenerated energy resources, solar energy and solar cell capable of converting sunlight into electrical energy are of the most promising energy industry, since sunlight is available all over the world, and it would not create pollution to the Earth like other energy resources (such as nuclear energy, petrochemical energy).

In case that the solar cell is provided with a large light irradiating area, then it can produce relatively large amount of electrical energy for use by various devices. Therefore, quite a lot of manufacturers hope to incorporate the energy saving concept into daily life of ordinary people, such as utilizing reusable solar cell in replacing the conventional disposable battery cells, so as to reduce pollution to the environment. In addition, the concept of “green energy building” can be combined with the solar cell, namely, putting solar cells in a building, where they are most exposed and irradiated by sunlight, such that the electrical energy generated by solar cell can be used to compensate for the electrical energy consumed by the building.

Presently, solar energy is most needed for agricultural green house and machine rooms of communication servers where constant temperatures are required, and in this respect, the conventional solar cell has much room for improvement.

FIG. 2 is a schematic diagram of office building having thin film solar cells according to a second embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed description with reference to the attached drawings. And, in the following, various embodiments are described in explaining the technical characteristics of the present invention.

Refer to FIG. 1 form schematic diagram of office building having thin film solar cell according to a first embodiment of the present invention. As shown in FIG. 1, the office building 100 comprises a building body 110 and at least a thin film solar cell 130. In the present embodiment, the building body 110 of the office building 100 can serves as an office room, a communication machine room, or a base station house, for the purpose of sheltering and protecting communication equipment 105 in the building body 110, and accommodating several operation personnel (not shown) to perform routine operations and maintenance as required. In some embodiments, communication equipment 105 includes wireless communication equipment, such as a large or medium size wireless base station, signal bridge, large signal transceiver (for example large directional antenna), etc.; or wire communication equipment, such as network address router, router, bridge, communication server, or optical fiber signal converter, etc.

As such, the building body 110 is provided with a top portion 120, and thin film solar cells 130 is disposed therein. To be more specific, in the present embodiment, the major characteristic of the thin film solar cells 130 is that, when sunlight L1 irradiates onto the top portion 120 of the sentry-box-shaped building body 110, the thin film solar cells 130 on the top portion 120 will absorb the green light, blue light, and ultraviolet light in sunlight L1 and converts them into electrical energy. In addition, the thin film solar cells 130 will reflect part of the infrared light and ultraviolet light that are not absorbed, such that the temperature inside the building body 110 is not apt to increase, so as to make it cooler and comfortable. Red light, yellow light, and yellow light in the sunlight L1 pass through the thin film solar cell 130 and reach inside of the building body 110 (dashed lines L1 as shown in FIG. 1), thus providing indoor illumination when the intensity of sunlight L1 is sufficient. In other words, in the present embodiment, the thin film solar cell 120 can be a transparent solar cell, such that red light, orange light, yellow light, and infrared light in sunlight L1 are apt to pass through the thin film solar cells 130, yet green light, blue light, and ultraviolet light in sunlight L1 are apt to be absorbed or reflected by the thin film solar cells 130.

In the present embodiment, the office building 100 may further includes a power source module 150, used for storing the electricity as converted and obtained by the thin film solar cells 130, and supplying the electricity to the communication equipment 105, air conditioner 170, or other electrical/mechanical devices in the office building 100. Since the electrical energy converted and obtained through the thin film solar cells 130 may offset or compensate a part of ordinary power consumption of the office building, thus it can save electricity expense. When there is surplus of this kind of converted electrical energy, power source module 150 may feedback the electricity and supply it to the power network or the Power Company, so as to earn some additional revenue.

In the present embodiment, the power source module 150 can be an uninterrupted power supply (UPS), and is connected electrically to a power supply socket; meanwhile, it may also store the electrical energy converted by the thin film solar cells 130 for supplying it to the wireless communication base station. Moreover, office building 100 may also include power supply device 155 (in the present embodiment, a diesel-fuel generator are taken as an example), so that when the power supply is interrupted, the power supply device 155 can be activated immediately to supply the power required, so as to maintain the normal operations of the communication equipment 105.

Furthermore, in the present embodiment, some of the equipment in the office building 100 can not maintain normal operations in high temperature, for example, communication equipment 105, uninterrupted power supply (UPS) 150, and power supply device 155. Therefore, in an office building 100, an air conditioner 170 is required to regulate room temperature, and that is located in a sentry-box-shaped building body 110 in regulating its inner temperature, and in cooperation with the functions of thin film solar cells 130 of reflecting part of the infrared light and ultraviolet light, temperature in the building body 110 can be maintained at a lower temperature. In this respect, power source module 150 and the thin film solar cells 130 may supply power to the air conditioner 170, so as to save air conditioning expense on electricity.

In the present embodiment, the top portion 120 of the building body 110 can be a detachable and replaceable structure, such that it is easy to replace any damaged or worn out thin film solar cells 130. In addition, the entire structure of office building 100 can be designed into a modular configuration similar to a kind of container house, so as to facilitate the assembly, installation, and transportation of communication equipment 105. Moreover, the office building 100 is also provided with a plurality of light-emitting-diodes 160 for illumination at night. To be more specific, the light-emitting-diodes 160 are arranged on the top portion of the building body 110, such that when in sunny weather and broad daylight, the portion of sunlight L1 passing through the transparent thin film solar cells 130 can be used for internal illumination of a sentry-box-shaped building body 110; and while in cloudy weather or at night, light-emitting-diodes 160 can replace light bulbs in providing sufficient illumination inside the building body 110, so that maintenance staff may carry on repair and/or maintenance of communication equipment 105 at night.

Furthermore, thin film solar cells 130 may also be connected electrically to the light-emitting-diodes 160 for providing them with the converted electricity. To be more specific, when in sunny weather and broad daylight, the portion of sunlight L1 passing through the thin film solar cells 130 can provide illumination inside the building body 110; and while in cloudy weather or at night, light-emitting-diodes 160 can provide sufficient illumination inside the building body 110, with its power provided by ordinary local power supply, in addition, the power stored in power source module 150 mentioned above can also be utilized, so as to save the local power supply utilized, in achieving “energy conservation and carbon reduction”.

It is worth mentioning that, in another embodiment of the present invention, the thin film solar cells 130 can be made into eaves on the top portion 120 of the office body 110, also thin film solar cells 130 can be placed on outer wall of the office body 110 to increase the receiving area of sunlight L1. Refer to FIG. 2 for a schematic diagram of office building having thin film solar cells according to a second embodiment of the present invention. As shown in FIG. 2, the top portion 120 of the office body 110 is extended outward into an eaves portion 210, that is made of thin film solar cells 130 so as to increase light receiving area and photoelectric conversion efficiency, moreover, it can also provide shelter against rains and strong winds. In addition, in the present embodiment, the outside walls 220 around the office body 110 are provided with thin film solar cells 130 (as shown by slant line in FIG. 2), so as to increase the light receiving area, and the photoelectric conversion efficiency of the thin film solar cells 130.

Summing up the above, in the present invention, thin film solar cells are provided on the top portion of a building body, such that when sunlight irradiates on the top portion of the building body, the thin film solar cells absorb the green light, blue light, and ultraviolet light in the sunlight, and convert them into electrical energy, and then provide it to the power storage device, air conditioner, or communication equipment, etc, in the office building, so as to save expense spent on electricity; while red light, orange light, yellow light, and infrared light will pass through the thin film solar cell, and reach inside the building body for indoor illumination of the office building. Since some of the infrared light and ultraviolet light are reflected by the thin film solar cell, the rate of temperature increase inside the base station house can be reduced, thus the internal temperature can be regulated effectively in cooperation with an air conditioner, hereby saving expense of electricity for the air conditioner. Furthermore, the present invention also provides a base station house based on the concept mentioned above.
